Knock Knock: Room Defense – How to Conquer Stage 204 Cemetery Laughter

Stage 204, titled "Cemetery Laughter," presents a significant challenge for players in Knock Knock: Room Defense. As you reach this mid-to-late stage threshold, the ghost's aggression increases, and your resource management must be near-perfect to survive the night.

This guide focuses on the specific build priorities and defensive maneuvers required to overcome the unique pressures of the Cemetery Laughter encounter.

Cemetery Laughter Stage Overview

In this stage, the ghost’s ability to chip away at your door durability while simultaneously pressuring your economic growth is the primary threat. If you focus too heavily on income, you will be breached; if you focus too heavily on defenses, you will fall behind on the technology upgrades needed to survive the final waves.

Recommended Defensive Priorities

To survive the relentless attacks in Stage 204, follow these tactical priorities:

Priority	Strategy	Goal
Door Integrity	Prioritize Tier 3+ door repairs immediately	Prevent early-game breaches
Bed Upgrades	Focus on rapid Bed Level 4-5 scaling	Ensure gold income keeps pace with repair costs
Turret Placement	Position defensive turrets to cover the front line	Reduce ghost proximity time
Tech Tree	Unlock advanced barricade modifiers	Slow down ghost movement speed

Tactical Execution for Stage 204

1. The Early Game Economy

The start of Cemetery Laughter requires a "greed-first" approach. You must invest in your Bed level immediately to ensure that by the time the ghost reaches your door, you have the gold flow necessary to sustain constant repairs. Avoid over-investing in low-level turrets that lack the DPS to actually kill the ghost at this stage; instead, put those resources into your door's durability.

2. Managing the "Cemetery Laughter" Ghost

This specific stage features a ghost that benefits from prolonged engagement. To counter this:

Constant Repairing: Do not let your door health drop below 50%. The ghost gains a hidden speed or damage buff if your door health enters the "critical" red zone.
Active Defense: Keep your finger on the repair button. In Knock Knock: Room Defense, human reaction speed is your best defensive layer.
Turret Synergy: If you have unlocked the "Slow" or "Freeze" type turrets, position them nearest to the door to maximize the time the ghost spends within the range of your high-damage weaponry.

3. Mid-Stage Pivot

Once you hit the middle of the night, the ghost will likely attempt a sustained assault. This is the moment to stop all Bed upgrades and dump every unit of gold into:

Door Reinforcement: Maximize the highest tier available.
Turret Upgrades: Focus on single-target damage to force the ghost to retreat.

Common Mistakes to Avoid

Over-extending on Beds: Do not upgrade your Bed if it leaves you with zero gold. Always keep a "safety buffer" of gold for at least two consecutive repairs.
Ignoring the Door: Many players rely too heavily on turrets. In Stage 204, the door is your primary shield—treat it as the most important unit in your build.
Panic Upgrading: Avoid upgrading random buildings. Stick to the Bed-to-Door-to-Turret loop to ensure your progress remains efficient.

By focusing on rapid economic scaling early and shifting entirely to defensive sustainability as the ghost intensifies its assault, you can clear Stage 204 and move on to the challenges ahead.
